  * SystemFileDescriptor is returning current Limit & max system limit for file descriptor (open file or I/O resource) currently set in the system
  * This function return the current setting (current number of file descriptor and the max value) if the newValue given is zero
  * Otherwise if the newValue is more than the current system limit, try to change the current limit in the system for this process only
+ *
+ *  For Windows build, please follow this note :
+ *	1) install package gcc-multilib gcc-mingw-w64 to build C source with GCC
+ *		you will having this binaries
+ *			- i686-w64-mingw32* for 32-bit Windows;
+ *			- x86_64-w64-mingw32* for 64-bit Windows.
+ *		locate you binaries gcc mingw path and note it:
+ *			- win32 : updatedb && locate i686-w64-mingw32-gcc
+ *			- win64 : updatedb && locate x86_64-w64-mingw32-gcc
+ *	2) if you have an error in the build, or if the .o object file is not present in golib/njg-ioutils/maxstdio/, run this step
+ *		- go to golib/njg-ioutils/maxstdio folder
+ *		- gcc -c maxstdio.c
+ *	3) for Win32 use this env var in prefix of your go build command (recommend to use -a flag) :
+ *		CC=/usr/bin/i686-w64-mingw32-gcc CGO_ENABLED=1 GOOS=windows GOARCH=amd64 go build -a -v ...
